Additional Notes

  • The rear door panel and front door panel locations in the 2020 Chevrolet Blazer appear to be the higher-priority replacement positions, given that they accommodate larger drivers such as 6.5-inch midbass or full-range units and 6x9-inch full-range speakers, which tend to handle a broader frequency range and greater output compared to smaller positions.
  • The front door panel's 6x9-inch full-range compatibility may suggest a wider cone surface area, which could contribute to improved low-frequency reproduction relative to the smaller positions in the vehicle.
  • The dashboard tweeter position, rated at 1 inch, may indicate a dedicated high-frequency driver, which typically operates in the upper treble range without low-frequency responsibilities, suggesting a possible factory crossover arrangement is in place or may be required for proper integration.
  • The center dash position accommodates a 3.5-inch full-range driver, which could handle midrange frequencies reasonably well, though its smaller cone size may limit bass extension compared to the door panel locations.
  • Replacing the rear door panel drivers with midbass-oriented units could potentially improve lower midrange reproduction in the rear soundstage, while opting for full-range units there may offer a more self-contained frequency response without requiring additional crossover components.
